Name the balls as 1,2,3,4,5,6,7,8
Pick first 6 (or any 6) balls and put on either side of balance
Case 1:
If it matches then take remaining to balls say 7 and 8 and put on either side. Now which ever is heavier is the one
Case 2:
If first 6 does not match, then take the 3 balls from heavier side and pick any 2 of them and weigh it.
Case A:
If not same then the heavier is one.
Case B:
If same then the remaining 3rd ball is the heavier one

We need to use class loader to instantiate the class. Class.forName internally uses class loader. Not sure if this helps...

Thank You

We need to use multi threaded environment here
